go-daikin's Introduction

go-daikin - Daikin AirCon controller

This package provides an API for probing and controlling Daikin split systems fitted with a Wifi controller module.

This package is tested against the BRP072A42 interface.

Features

Discover devices on the local network
Query and set current operating parameters
Query current sensor values

Basic usage

Querying status for discovered devices:

package main

import (
  "fmt"

  "github.com/buxtronix/go-daikin"
  "github.com/golang/glog"
)

func main() {
  d, err := daikin.NewNetwork()
  if err != nil {
    glog.Exit(err)
  }
  if err := d.Discover(); err != nil {
    glog.Exit(err)
  }

  for addr, dev := range d.Devices {
    if err := dev.GetControlInfo(); err != nil {
      glog.Error(err)
      continue
    }
    if err := dev.GetSensorInfo(); err != nil {
      glog.Error(err)
      continue
    }
    fmt.Printf("%s:\n%s", addr, dev.String())
  }
}

Set state for a specific device:

package main

import(
  "flag"
  "fmt"

  "github.com/golang/glog"
  daikin "github.com/buxtronix/go-daikin"
)

var (
  address = flag.String("address", "", "Address of daikin unit")
)

func main() {
  flag.Parse()
  d, err := daikin.NewNetwork(daikin.AddressOption(*address))
  if err != nil {
    glog.Exit(err)
  }
  dev := d.Devices[*address]
  if err := dev.GetControlInfo(); err != nil {
    glog.Error(err)
    continue
  }
  if err := dev.GetSensorInfo(); err != nil {
    glog.Error(err)
    continue
  }
  fmt.Printf("%s:\n%s", addr, dev.String())

  dev.ControlInfo.Power = daikin.PowerOn
  dev.ControlInfo.Mode = daikin.ModeHeat
  dev.ControlInfo.Fan = daikin.FanAuto
  dev.ControlInfo.Temperature = 22.5

  if err := dev.SetControlInfo(); err != nil {
    glog.Exit(err)
  }
}
